Details
What we tuned for this language
Built for interruption
English is where most voice agents start, and an agent lives or dies on the gap before it starts speaking. Kugel 3 streams audio as the text arrives, so the first syllable leaves the server long before the sentence is finished.
Acronyms, numbers and money
Order references, amounts and abbreviations are the sentences a demo never contains and production is full of. Our normalizer decides where to read letters individually and where to read a word, before synthesis.
Brand names, said your way
Every company has a handful of words that generic TTS mangles. Put them in the pronunciation dictionary once and every English voice on your account says them identically.
FAQ
English text to speech: common questions
How many English voices are on this page?
There are 5. Each one is a separate speaker rather than one voice with a pitch shift, and the same Kugel 3 model also speaks the other 25 languages we support.
Is it fast enough for a live voice agent?
Yes. The API streams over WebSocket and starts returning audio before the text is complete, which is what keeps a phone call from sounding like a walkie-talkie. It drops directly into Pipecat and LiveKit pipelines.
Can I use it for commercial products?
Yes. Paid plans include commercial use, and there is a free tier to test with first. Pricing is per generated second, with no per-voice licence.
